SELF-INSULATING CONNECTOR Filed Oct. 25, 1959 INVENTOR. F. E. Ll VE LY BY W44.- 4? 22/ ATTORNEY United States Patent 3,011,010 SELF-INSULATING CONNECTOR Frederick E. Lively, Fairborn, Ohio Filed Oct. 23, 1959, Ser. No. 848,480
4 Claims. (Cl. 17484) (Granted under Title 35, US. Code (1952), sec. 266) The invention disclosed herein may be manufactured and used by or for the United States Government for governmental purposes without payment to me of any royalty thereon.
This invention relates to a self -insulating connector adapted to be used to splice together two or more electrical wires.
, An object of the present invention is to provide a quick, safe device for connecting together two wires or a multiple of wires. I
A further object of the present invention is to eliminate the necessity of soldering the wires and then applying tape or plastic spaghetti for insulation.
According to the present invention the self-insulating connector comprises an elongated metal connector having a solid central middle portion and enlarged end portions with openings therein to receive the uninsulated wire ends, said connector is provided with an elastic in sulating covering of rubber tubing of greater length than the connector, said rubber tubing is secured at its midportion to the mid-portion of said connector, a throwaway yoke or clip is positioned over the connector to hold the rubbertubing axially compressed thus exposing approximately of the conductor adjacent each end of said yoke or clip.
These and other objects andfeatures of the present invention are described below in connection with the accompanying drawings wherein:
' FIG. 1 is a side view of the present invention prior to removal of the throw-away clip;
FIG. 2 is a sectional view of the present invention 0 with the throwaway clip removed, taken along the line 2-2 of FIG. 1; v
*FIG. 3 is an end view of the present invention as shown in FIG. 1.
Referring now in detail to the drawings wherein like reference numerals designate like parts and more particularly to FIG. 1 there is shown the self-insulating connector of the present invention generally designated 20. The self-insulating connector 20 basically comprises an elongated metal connector 22, rubber tubing 24 and a throwaway clip or yoke 26.
The metal connector 22 is provided with a solid central middle portion 28 and an opening in each end providing communication with the middle portion terminating in enlarged end portions 30. Said enlarged end portions 30 are provided with both enlarged external and internal diameters. The elastic insulating rubber tubing 24 is of greater length than the metal connector lobe-shaped arms 36 depending therefrom. A slot or opening 38 is disposed in each of said arms extending from a point on the lower periphery of said lobe-shaped arms to a point approximately midway between said lower periphery and said flat top portion 34.
The width of said slot 38 is no greater than the diameter of the metal connector intermediate its enlarged end portions. The distance separating the depending arms 36 of the clip or yoke 26 is approximately /2 the overall length of the metal connector 22. I 1
3,011,010 Patented Nov. 28, 1961 ICC.
In operation the self-insulating electrical connector of the present invention initially appears as shown in FIGS. 1 and 3 with the elastic rubber tubing 24 held in an axially compressed position on the metal connector 22 by means of the arms 36 of the yoke or clip 26. The yoke or clip 26 is held firmly on the metal connector 22 by means of a press fit between the slot 38 in the slightly resilient arms 36 and said connector. When the rubber tubing is thus axially compressed approximately A of the length of the metal connector will be exposed at each end. j I
To splice or connect electrical wires the wire or wires 40 are inserted into the open ends of the elongated metal connector 22 to the extent that they abut the solid central middle portion of the connector. The metal connector 22 is then crimped onto the uninsulated ends of the Wires by means of a suitable tool at a point 42 intermediate the arms 36 of the yoke or clip 26 and the enlarged portion 30 of the metal connector. The splice is completed and insulated simply by removing the throwaway clip 26 which permits the rubber tubing 24 to immediately expand to completely cover the connector 22 and the adjacent ends of the wires 40.
It is to be understood that no limiting dimensions have been disclosed in connection with the self-insulating connector of the present invention since it can obviously be manufactured and used for connecting or splicing infinite numbers and sizes of wires.
The present invention has been'described in detail above for the purpose of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims.
I claim:

2. A self-insulating electrical connector of the type described comprising an elongated metal connector having a solid central middle portion and enlarged end portions, an insulating cover of elastic rubber tubing of greater length than said metal connector, said rubber tubing being secured at its mid-portion to the mid-portion of said metal connector, a throw-away clip having a flat top portion and a pair of spaced lobe-shaped arms depending from opposite ends thereof, means in each of said arms for releasably gripping said metal connector, said arms being positioned on said metal connector maintaining said rubber tubing in axial compression therebetween thus exposing approximately of said metal connector ateach end, said clip being adapted to be removed from said metal connector thereby releasing said elastic rubber tubing from its axially compressed state and permitting it to expand out over the ends of said metal connector.
3. A self-insulating connector for joining the uninsulated ends of wires comprising: an elongated metal connector; means at each end of said elongated metal connector for receiving the uninsulated ends of wires; an elastic, tubular, insulating member of a length greater than said elongated connector and surrounding, when axially compressed, at least the central portion of said elongated connector; releasable means positioned on said elongated connector adjacent said elastic insulating member for retaining said elastic insulating member in an axially compressed condition thereby exposing the ends of said elongated metal connector to permit coupling of the Wires to said connector.
4. A self-insulating connector for coupling the uninsulated ends of wires comprising: an elongated metal connector; openings at each end of said elongated metal connector for receiving the uninsulated ends of Wires; an elastic, tubular insulating member of a length greater than said elongated connector and secured thereto, said elastic member surrounding, when axially compressed, at least the central portion of said elongated connector;
